I'm curious about seeing a provider that's UTR. Is there any way to find reviews for UTR providers or not? I suppose it would  defeat the purpose of being UTR but I'm fairly new to all of this and thought I should ask. Is there any solution to this?  
Thanks

n most cases, the UTR gals that I have met were (and in some cases still are) gals who I got to know at MPs, and decided to start meeting off campus.  They have no website, do not place ads, and don't consider themselves to be escorts.

Being under the radar means she does not want anyone to know (I assume in her real life) to know what she is doing on the side.  So, to answer your question, you will probably not find any reviews for a provider who is totally UTR.  You are at a dead end, IMHO.  While I have not seen a provider under these circumstances, and if I had, I would honor her request to not post a review.  You will have to find them from other providers you know, or hobby buddies who will vouch for you.

...that they remove their website, TER profile and reviews and see only regulars and referrals.   Since they have no internet presence, they can't be reviewed - hence they are UTR.  

What is this mystique that guys find with UTR gals?

Correct. I have several UTR friends with no internet persona whom I refer only to gents I have personally seen or at least know very well. Most of them absolutely refuse to put any photos on adult sites... even fully clothed.

That has not been my experience at all. I've known a couple who were just absolutely phenomenal. They did it when they need some financial assistance.

But I haven't experienced that.  I meet with a UTR that remains BY FAR the best experience I've had.  She just needs some extra money, I provide that and we get busy for a couple of hours every week.  

an internet presence isa TER requirement.  There's one gal I never could review because she didn't have ads anywhere that TER would accept.

A nice provider may have references from doing doubles with or handling referrals from another highly rated provider who can give a reference.
